The main purpose of this study was to comprehensively evaluate the local agenda 21 of Daegu City based on the evaluation model and propose important measures to solve its problems and improve the limitations. As a whole, the evaluation result of the local agenda 21 of Daegu City showed very low score, only 151 points out of 500 points and revealed it was below the level in all three domains of making process, designed content, and evaluation of implementation. The making process got only score below the half in all large indicators of understanding, driving, and rationality. This unsystematic and irrational process inevitably resulted in ambiguous and proclamatory content mainly expressing willingness to do. This fact means that the local agenda 21 of Daegu City has not served as the comprehensive local environmental plan containing visions, policies, ends and means. It did not suggest evaluation system and institutionalization of evaluation. These results of evaluation suggested that the existing local agenda 21 of Daegu City was neither useful nor effective and thus the totally new local agenda 21 should be prepared. Finally, important measures in making process, designed content and evaluation of implementation were proposed for the remaking.

This study was conducted to develop the evaluation model which can analyse local agenda 21 comprehensively and systematically from the making process to the designed contents. The evaluation model was devised through the theoretical review of local agenda 21 and designing the evaluation system composed of evaluation domains, related indicators and scales. The evaluation system was carefully constructed based on planning theories and the discussion and agreement of specialists regarding local agenda 21. This model has three evaluation domains of process, content, and evaluation of implementation with different weighting values. Each domain contains large indicators, medium indicators and small indicators. Each indicator has different weighting value according to its importance. Basically, each small indicator was scored by 3 or 5 point scale. This evaluation system can not only analyse local agenda 21 quantitatively, but also find out good points, problems, and limits of various phases of planning and implementing local agenda 21.

This study was conducted to develop the questionnaire for the measurement of environmental attitudes and test its reliability and validity. Development and validation of the 46 survey items that measure environmental attitudes were described. The total of 3 surveys were conducted and the total of 510 persons including diverse sample groups were questionnaired. The SAS PC+ package program was used in both the reliability analysis and the validity analysis of surveyed data. Results revealed the very high reliability and the high validity of the questionnaire. The reliability of the finalized questionnaire was increased to the level of Cronbach-α 0.92 after the repeated reliability analyses and revisions of the firstly and secondly designed questionnaires. The validity of our questionnaire was sufficiently affirmed through the use and application of factor analysis and known-groups technique.

Volatile organic compounds(VOCs) are of concern for their potential chronic toxicity, their suspected role in the formation of smog, and their suspected role in destruction of stratospheric ozone. Present study evaluated the exposures to selected VOCs in three microenvironments: 2 chlorinated and 5 aromatic VOCs in the indoor and outdoor air, and 5 aromatic VOCs in the breathing zone air of gas-service station attendants. With permissible Quality Assurance and Quality Control performances VOC concentrations were measured 1) to be higher in indoor air than in outdoor air, 2) to be higher in two Taegu residential areas than in a residential area of Hayang, and 3) to be higher in the nighttime than in the daytime. Among five aromatics, Benzene and Toluene were two most highly measured VOCs in breathing zone air of service station attendants. Based on the sum of VOC concentrations, the VOC exposure during refueling was estimated to be about 10% of indoor and outdoor exposures. For Benzene only, the exposure during refueling was estimated to cause about 52% of indoor and outdoor exposure. The time used to calculate the exposures was 2 minutes for refueling and 24 hours for indoor and outdoor exposures.

This paper evaluates the historical development of national park policy and administration in Japan from the perspective of achieving sustainable development in nationally important ecological areas. Contrary to the widely held belief, the national park system in Japan has been unsuccessful in balancing conservation and development. The fundamental reasons for its failure are as follows: the Japan`s national park system has been largely founded and developed based on economic grounds and held sway by economic development policy; the policy and administrative coordination between government units concerning conservation and development has not been carried out; public participation and environmental groups` involvement in the decision making have been extremely limited; national parks have been perceived in the public image not as distinctive national heritage but as finest and popular tourist sites; and the dominant interest of tourism and recreational development has prevailed over conservation interest. Japan`s unsuccessful experience and lessons imply that there is urgent need to drastically reform our national park system, largely founded on the Japanese model, in order to save our last national environmental heritage.

Recycling is receiving increasing social attention today as our nation begins to grapple with the significant problems caused by huge amount of municipal solid waste. The topic of recycling is not simple but extremely complicated. This study attempts to provide basic data and policy options for expanding and improving separated collection and recycling in public residential areas, through three case study of apartment housing areas in Taegu Metropolitan City. The main results of this study are summarized as follows. For the significant period of time, all three case areas had in common the extreme difficulty in establishing and operating the system of connecting public participation, collection and storage, transportation, and actual recycling of materials because of a variety of problems involved in this process. Both amounts of and prices for collected materials fluctuated considerably over time mainly due to monthly changes in recyclable home materials and the dynamic nature of recycling markets. Public questionnaire survey revealed the very high level of participation in separated collection, not only because almost all respondents well understood the necessity and importance of recycling, but because they also knew how to do separated collection. But overall activities were rated low and most respondents suggested the enlargement of public participation, the improvement of collection and storage facilities, and collection transportation networks. In particular, most respondents had little experience of using recycled products and used mainly reproduced soap and bathroom tissue. Furthermore, they were considerably unsatisfied with low variety and quality of recycled products, their high prices and low availability in the market. Finally potential policy options and activities for improving separated collection and recycling are suggested.
